usb 2 not working ... need help please ..

hi guys i have a wii with system 4.3e that is softmodded . with your brilliant 4.3 guide on here i used the yu gi oh hack .. and i have usb loader working .. i have been using this for a while now .. i have every game working . and have updated to the latest cios 249 v20 .
i am now asking if anyone could help me ..
my question is i have just been given the microfones for ww sing and i have my external hard drive plugged into slot 1 when i plug my mic in to slot 2 it does not work ..
i even went out and bought the wee sing game but when i put the disc in it asks for the system update so i jus dont play it ..
can you please advise me of what i can do please ..
much appreciated ....

You must have skipped the section in the guide tha tells you to install PRIILOADER.Go back and do that step, it will solve your "update" issue. I think there is a guide somewhere about the mic problem, do some searching.
